| 摘 要： | 提出了能有效提高电网消纳风电等间歇式能源能力的发电计划在线滚动修正策略,并给出了其与日前计划优化的关系。同时,给出了相应的优化调度模型。基于拉格朗日对偶松弛法的框架,将原优化问题转换为拉格朗日对偶优化问题的主问题和子问题两部分。然后,基于模型凸规划的特点,提出了子问题的逆向递推的改进动态优化算法。该算法具有多项式复杂度...

| Abstract: | A strategy for on-line rolling generation dispatch is proposed for effectively accommodating large-scale wind power,and its relationship with day-ahead scheduling is given.A mathematic model for on-line rolling dispatch is also given.Based on the framework of Lagrange dual relaxation,a primary problem is transformed and decomposed into primal-problem and sub-problem of a dual problem.Then,an improved dynamic programming is developed for sub-problem based on the feature of convex function.The proposed method... |
